srooL FOR MUSIC-ROLLS.

. To all w7wm it'may 4 z Be it known that I, l-YiLLIAM S. DENTON,

, a. citizen of the United States, residing in New. ork-c1ty, in the State'biNew lork, hauemvented certain neyvand useful Improvements in Spools ,for Music-Rolls, of winch the followingis a' specification.

- Tl1iS invention relates to spools for music sheets or rolls suchfas are employed in sefplayin '.musical instruments, and the oh the invention are .to provide an improved construction of spool which is adustable longitudinally; to enable such adjustmentto be effected between the endflanges of the spool or outside of the same,

or both; tothus enable-the spindle of the spool to be lengthened or Shortened to compensate for variations in the width of the music lsheets due to atmos heric or other conditions, and also to enab e the end bearings-of thee ;t 1 to be moved toward or away from earspindle adjustineiit; to thus secure great exaotnes's and uniformityin the operation of the spool and a consequentperfect action of the music sheet; toprovide a simple. inexher independently of said pensiveand durable construction, aud t-o obtain other advantages and results asimay be brought dut in the following description.

Referrin to the accompanying drawings,

- in which'li .e numerals of reference indicate the same parts in the several figures, Figure I 1 is. aside view ofa spool embodying my invention: Fig. 2 is a side view of an adjustable end section and Fig. 3 is a view of the same from .its inner end, Fig. 4 is a side view of a portion of the spool, partly in cenis made up of two sections 4 and 5 tral longitudinal Y section -to illustrate the connection of itsadjusta-ble sections; Fig. 5 is a side view' of an end portion of the spool,

artly in central longitudinal section and illustrating the end-bearing or phi, andFig. 6 is a side view of said end bearing or pin, lookin at it in a. direction at right angles to that 0 Fig. 5.

In said drawings, 1 indicates a spindle having shouldered and reduced ends 2, 2 on which are mounted the usual disks or flanges 3, 3, to form a spool for a perforated music sheet. .These flanges may be loose on the ends 2 but are generally set tight thereon, and in -either case the shoulders will prevent their movin inward so as to interfere with the action 0? the music sheet. Said spindle adjustable l Specification or Letters Patent. App1icatl on filed February 11, 1908. Serial mi. 416,332.

- of such width as to allow with res ect to each other longitudinally of the spool in order to provide lateral ad ustment to take up the expansion, contraction, or other variations. in the width of music sheets: It is to the means for connectin and adjusting these sections of the spind e to which my invention relates in part, and these means will be next described. The inner end of the long section 4 is bored out or socketed, as ,at 6, and the adjacent or inner end of the other or short section 5 has a shoulder and an extension 7 reduced to a diameter which is normally slightly larger than the bore of the said socket 6 in sectlon 4. Said reduced end 7 is provided with longitudinal saw kerfs or slits 8, preferably two at right angles to each other in end view, as shown in Fig. 3. These slits are by the slitted extension 7 tobe compressed so as to enter the socket 6 and fitnicely therein or with considerable friction. Furthermore, the slits 8 preferably extend beyond the shoulderat the 'end extension 7 a. short distance into the spindle section. 5,

as shown in the drawings. This gives the fingers formed Patented March 9, 1909.

greater resiliency to the longitudinal fingers into which the slits divide the end extension 7, particularly near their bases, and permits them to be compressed or approximated throughout their entire length, and insures that said fingers will hold firmly in -the socket in any position. I consider four. fingers (or even three) preferable to two, as the latter will allow deflection of the members in a plane through the slit between the fingers, whereas a greater number than two will not. In use of the spool, the fingers of the section 5 are pushed into the socket 6 any desired distance to accommodate the width of a perforated sheet wound on the spool; if by reason of dampness or heat the paper should expand or contract, the sec-' opportunity to adjust the hearings in compensation of longitudinal shifting of the sections of the spindle.

A second feature of my improved spool.

and which feature will now be described, is

to enable adjustment of the end bearings and independently of the spindle. One end of the spool is provided with a. lined pin or stud 9, but the opposite, and preferably the driving, end of the spool has a pin or stud 10 which is threaded as at 11 to screw into the end of the spindle and can thus be moved out or in as is desired. -Adjaceut to said threaded portion 11, the pin or stud 10 has at opposite sides of itself transverse wings 12 pinched or raised up outof the body of the pin, and which wings serve as a fixed stop to engage the bearings (not shown), instead of the end 2, of the spindle. Still further out than the wings 12, are the usual longitudinally disposed fins 13 for engagement with the driving means.

The music sheet, it will be understood, is attached to the long section 4 of the spindle, leaving the snort section 5 free for adjustment as described to vary the length of the spindle or distance between the flanges 3, 3. If adjustment of the spool to its bearings is needed, the pin or stud 10 is screwed in or outfo the proper point. In some cases both adjustments may be employed to advantage,

My improved spinal thu m ed.- oi :.:2 possible adjustments which ran dean-d. and each adjustnwnr can he ma-le iihlcpu'zniently:

Having thus described illtdlH'ltllliflll, in! I claim as new is z 1. in a spool for music rolls, a spindle comprising two section of snbdantially alasame diameter, one having a socket bored in its end and the other having a- I'Qtllttttl extension of larger diameter than aid Stflkkt. said extension having a plurality of diametric slits extending lomg'itmlinall o itself and into the body of the section havin said extension, whereby the ester-ion 11.43: lucompresse'd as slid longitudinally into tlusocket in frictional holding engagenn-n: therewith.

'2. In a spool for music rolls, the combination with two sections having flanges near their outer ends, and means for teterscupicrally adjusting the sections on each other between their flanges; of a pin or stud at eachof said section ends, means for adjust ing one of said pins or studs longitudina ly of itsect-ion, and a bearing portion on the pro- 'ectin art of each in. 1 p WiLilLtM s.
